VAEGE-CONDENSING: APPARATUS.

Application filed April 19, 1920. Serial No. 375,145.

To aZZ whom it may concern:

Be it known that 1, WILLIAM PARIS BAR- CLi r, a citizen of the United States, residing at Chicago, in the county of Cook and. State of Illinois, have invented certain new and useful improvements in Vapor-Condensing Apparatus in Relation to Steam Heating of Buildings.

This invention relates in general to means for condensing the water vapor issuing from a pipe coil system, such as used in buildings for heating purposes.

in steam heating systems, provision is generally made for the return oi: the water vapor from the pipe coils, or a system of radiators, by the use of a return pipe or pipes that are connected in a suitable manner to a reciprocating pump that ultimately returns the water of condensation back to the steam boiler forming part of the steam heating system of the buildin The rapidly increasing use or" electric power in public buildings makes possible a change from a slow moving reciprocating steam pump method to one that will operate at a high speed by the use of a high speed centrifu al or rotary pump, in connection with an ejector-condenser as a part 01: a high speed system, whereby certain advantages are attained over a slower method.

My new method consists in the combination of a centrifugal pump with an ejectorcondenser, whereby the said pump is used to force water as a condensing medium through an ejector-condenser, and condense the vapor supplied to the ejector-condenser, the said centrifugal or rotary pump being actuated by an electric motor preferably direct connected to the pump, and other parts in connection therewith, that will be fully explained in detail.

The original ejector-condenser was conceivcd and constructed to displace the air pump and condenser of a condensing steam engine or to perform the work thereof, and in its new relation to a steam heating sys tin l have adopted the ejector-principle to condense the vapor from a pipe coil, or radiator heating system, and by causing a rapid circulation of water through the ejector-condenser by a centrifugal or a rotary pump rapid condensation of the vapor occurs on entering the ejectoncondenser, and the condensate is instantly ejected into water compartment of a tank which is connected with the inlet side, of the centrifugal pump.

in the drawings:

Fig. 1, shows front elevation partly sectional, of the apparatus.

Fig. 2, shows an elevation at a right angle to Fig. 1.

Fig. 3, shows a plan paratus.

Fig. 4, shows an ejector-condenser adapted to meet its new requirements in relation to the vapor and water compartments or a tank.

Fig. 5, is an exterior elevation of the ej ector-condenser.

ig. 6-, is a sectional view through line 6, 6, of Fig. l.

Fig. 7, shows a plan view of the upper head of the ejector-condenser, and parts in relation thereto.

Similar letters refer to similar parts throughout the several views.

".The base supports a metal tank C, a centrifugal pump D, and an electric motor E, that the entire apparatus can be easily transported.

The tank U is divided into two compartments by the division plate 0 the compartment 0 is for water and t is compartment 0 is for vapor the return pipe.

The centrifugal pump D is preferably driven direct by electric motor E without any belt or intermediate gear, so as to view of the apavoid unnecessary vibration and noise, and I the said pump is means or causing a rapid c ulation of ater to occur between the compartment 0 of the tank C and the interior of the ejector-condenser F, that is attached to the upper head 0 oi the tank C.

The ejector-condense F, is shown in enlarged views in Figs. l, 5, 6, 7, and the sectional view represented in 6, illustrates the interior construction on line 6, 6, of the ejector "ondenser. in an ejector-condenser the most efficient operation, the cirpassing through the ejector- 1:561 should move downward, so that condo; the on turthe nozzle censer treme end of the discharge pipe 01 of the cenculated water is instantly freed from obstruction on leaving the lower 8 oi"- the ejector-condenser. water inlet port of the ejector-conis for pipe connection with the extrifugal pump D, and the water on entering the ejector-condenser immediately moves downwards, and passes through the nozzles l 2, 3, or" the ejector-condenser into the water compartment 0, of the tank 0, for further use as a condensing medium, or as feed water to a steam boiler, according to change:

throughout the heating condenser is controlled in its action by a float G acting through a stem 9 thatcauses the fulcrum lever h pivoted to a post 4) to alternately rise up and move down and operate through an intermediate link a the lever i that is rigidly attached to a spindle is pivoted to the body of the ejectoncondenser.

The pivoted spindle operates the lever 1" that connects to the water control stem 7 of the ejector-condenser.

The stem 9 of the float at its upper end is formed with an oblong opening to permit the float G to rise and fall with the water Withinthe compartment 0 of the tank more or less of a limited distance, without causing the water ccntrolstem 7 to move either up or down, and the operation of the water control stem is performed during the last few inches of the rise and fall of the water in the compartment 0, of the tank C, and when the water in the compartment c of the tank C has reached its highest level, the water control stem 7 is then at its lowest position in the nozzle 1 of the ejector-condenser, and the condensing water is then shut OK, so that it cannot pass through the ejector-condenser, but the centrifugal pump remains in operation and lowers the water in the compartment 0 of the tank a greater or less distance by discl'iarging it through the branch g, until the current is cut oil that operates the electric motor E.

The vapor inlet ports 39 to the ejector-condenser, permits vapor from the compartment 0 of the tank to pass between the nozzles 1, and 2, of the ejector-condenser, and meet the circulated water at the space between the ends of the nozzles l, and 2. t

The vapor inlet ports 39 of the ejectorcondenser permit vapor from the same compart-ment c to enter the ejector-condenser and pass between the nozzle 2 and the outer wall or" the ejector-condenser, and meet the circulated water for vapor condensing purlated water, and the water due to vapor condensation is ejected into the water compartment 0, of the tank 0.
